Abstract: The combustion experiments of cornstalk were conducted under different heating rates using the thermogravimetric analyzer. Combustion characteristic curves and combustion characteristic parameters were acquired. The research results showed that the combustion process of cornstalk can be broadly separated into three stages: evaporation of water, release and combustion of volatile, combustion of fixed carbon.The cornstalk has a a

dvantage of low ignition, better burnout as well as high combustion rate.It was observed that the delayed temperature of ignition and burnout and raised reaction rate can be achieved with the addition of heating rate. The result showed feasibility of using first order reaction model to solve the kinetic parameters of cornstalk combustion.
